The system includes a smoke chamber. This chamber can vary in size and shape. The cigarette, cigar or pipe is placed into the chamber. The device draws the smoke from the lit cigarette and the like and pulls it through the Vacuum System and then blows it out through a venting apparatus or even an outside window. The size of the system will vary according to usage. Single usage is possible or multiple users can be accommodated on a larger system. The Smokers Vacuum system is practical for residential use or can be built for commercial use. i.e. a restaurant or night club or a public area. There can be one hose leading from the smoke chamber to the motor chamber for a single user, or there can be many smoke chambers leading to the motor chamber for many users.

Industrial filter asembly - has suction cleaning ring round it moved along drum filter structure

Industrial filter assembly, with a cleaning mechanism, has a drum-shaped filter with a suction ring round the filter drum, and a suction slit against the filter. The suction ring is moved along the line of the filter axis, in a forwards and backwards sliding action. The suction ring is pref. moved by a linear component (11) for a slide carrying the ring. The filter material has an elastic distortion where the outer dia. of the filter can be reduced from its relaxed size which is larger than the inner dia., of the suction ring. The linear movement system is controlled by pressure sensors which register the pressure at the clean air side of the filter or the difference in pressure between the two sides of the filter. USE/ADVANTAGE - The filter assembly is part of a dust removal system especially in industrial and commercial working areas. The filter is cleaned effectively by suction extraction, in a simple and cost-effective unit.

Filter for large quantities of dust-laden fluids - having perforated walls lined with filter cloth cleaned by rotating suction heads

The filter comprises a vertical cylindrical vessel of metal mesh closed at each end and internally lined with the filter cloth. The top end of the filter has a fluid inlet and an opening through which passes a rotating hollow shaft coaxial with the cylinder. Suction parts are fitted to the ends of arms extending from this hollow shaft which extends to the base of the filter. At least one suction pad sweeps the filter cloth surface and at least one sweeps the base. The hollow shaft is connected outside the top of the filter to a motor with gear reducer to rotate the shaft and to a fan which draws air through the shaft. Inside the casing on the upper part of the shaft are two diametrically opposed arms at the ends of which are suction pads that sweep the whole of the filter cloth. On the lower part of the shaft are two diametrically opposed arms having suction pads that sweep the floor. The outlet of the fan is connected to a cyclone for dust removal. Filter is used for cleaning large volumes of dust-laded gases, e.g. flue gases. It is compact which gives a lower capital cost and can work continuously. Power consumption is low for the volumes handled.

A method of cleaning filter bags, chambers, pockets or the like, which collect dust on their inner surfaces is as follows: at intervals, each filter is isolated from the incoming dirty gas stream and is suddenly connected to a vacuum system; thus the sudden creation of a vacuum inside the filter causes clean gas to be sucked back through the filter, thus removing the dust completely from inside the filter and conducting it out via the vacuum line.

Bag type air cleaning apparatus

TITLE: BAG TYPE AIR CLEANING APPARATUS Abstract of the Disclosure A bag type air cleaning apparatus is described for collecting particulate sediment from a source of pressurized air. The apparatus is adapted for connection to the pressurized air source and receives the pressurized air within a cylindrical plenum. A plurality of upright pervious bags are openly associated with the plenum for receiving the pressurized air. The air and particulate sediment is forced upwardly into the bags and against the bag interior surfaces where the sediment will collect as the air escapes through the pervious material. The bags are mounted on upright frames that are collapsible for storage purposes. A sliding duct is provided in communication with a blower mechanism in order to successively clean the inside surfaces of the bags. The sliding duct includes a manifold that comes into contact with successive openings of the bags while being pivoted about within the plenum. The manifold is connected to the blower mechanism which produces a suction force to reverse the pressure within the successive bags. The sediment is thereby pulled from the inside walls of the bags and is delivered through the sliding duct to a discharge. In addition, sediment will settle on the bottom or floor of the plenum. This sediment is gathered and delivered by an auger mechanism to the same discharge. A biased valve is associated with the auger to close and open alternately in response to outward pressure produced by the sediment being forced outwardly by the auger. Thus the sediment received from the sliding duct and from the auger is passed through the same discharge and is disposed of by the same blower mechanism.

The suction nozzle (6) may be connected to an external vacuum device, e.g. a vacuum cleaner, so that the pre-filter can be easily cleaned. The suction nozzle locally covering the outer surface of the pre-filter is to be movable parallel to said surface. The pre-filter is rotatable.

Filter cleaning apparatus and method

Apparatus for cleaning a high efficiency particulate air (HEPA) filter includes a vacuum system having a vacuum nozzle which spans the inlet face of the filter and a nozzle inlet lying closely adjacent the filter face. The nozzle inlet is dimensioned to effectively cover one or more two-cell filter modules formed by the filter media separators. A vacuum or induced draft is applied to the nozzle to provide a cleaning air flow counter to the flow of particulate air through the filter. The nozzle temporarily blocks or retards the flow of particulate air through the module or modules being cleaned while the flow and filtering of particulate air continues through the remaining major portion of the filter. Means and their corresponding method of operation for maintaining the nozzle in contact with the filter inlet face and for moving the same across the filter face for sequential cleaning of the filter modules are also disclosed.

Air inlet filter for gas turbine engine

ABSTRACT OF THE DISCLOSURE An annular air filter is rotationally mounted within a plenurn box, which in turn is securely mounted to the inlet end of a gas turbine engine. At least a portion of the annular air filter surrounds the inlet end of the engine. A motor is provided to rotationally drive the air filter relative to both the plenum box and the engine. An air pressure nozzle is disposed adjacent the inner circumfer-ential surface of the air filter, and a vacuum nozzle is disposed adjacent the outer circumferential surface thereof. The air pressure and vacuum nozzles clean the air filter as the air filter is rotated relative thereto.

Suction dredger

The invention relates to a dredger for the planned taking up of suction material, particularly for removing soil from underground pipes. The dredger has a pneumatic elephant trunk for taking up the suction material and which issues into a storage tank for the sucked up material and to which is connected an exhaust fan. In the storage tank the section material is separated from the suction air flag and is subsequently passed through a filter means positioned between the elephant trunk opening and the exhaust fan. In order to ensure a good separation on the part of the filter means for a long period of time, said filter means is formed by a coarse filter and a fine filter connected to the latter. The coarse filter is formed by a labyrinth or cascade-like flow channel, which is bounded by reciprocally displaced partitions and whose flaw cross-section increases in the flow direction. On the tank bottom can be provided a conveying means by means of which the suction material separated from the air flow can be removed continuously or at intervals from the storage tank.
